Beginner: I learned about the basic features of a layer-3 Switch. Some time ago, my colleagues asked me questions about the basic features of the layer-3 Switch. At that time, I did not give a positive answer, I was also the first to have a problem with the basic features of a layer-3 Switch. In the following days, I checked the relevant information and was satis

Hello, C ++ (20). 4.2.2 represents the switch statement selected by the parallel condition: if ...... If ...... If ......,. 4.2.24.2.2 expression of the switch statement selected by the parallel condition: if ...... If ...... If ...... In the real world, there are also such special conditions: If tomorrow is Sunny, I will wear a T-shirt; If tomorrow is cloudy, I will wear a shirt; If it is rainy tomorrow, I

Lan exchange technology can also be called layer-2 Switch Exchange Technology, the content mainly includes the working principle of Layer 2 switching, network loops, and how to use the Spanning-Tree Protocol to solve Network loops, VLANs, and VTP technologies, this article mainly introduces the working principle of L2 switches and the dangers of network loops. Other content will be introduced later. We all know that the traditional shared Ethernet use

With the further construction of China's information network, the further improvement of network quality, high-speed, high-performance Ethernet switch will become the mainstream of network product development. switch is an essential equipment for the network of large and medium sized enterprises, it plays a very important role in network construction, it can increase network capacity and improve network s

This digest is from http://www.pconline.com.cn/pcjob/ittest/network/0312/258919.htmlOther literature http://www.jztop.com/s/jiaohjjs/ Comparison of three-layer switch and router In order to meet the challenge of deepening the network application, the network has been developing rapidly in both scale and speed, the speed of LAN has been improved from the initial 10mbit/s to the 100mbit/s, and the Gigabit Ethernet technology has been widely used at pres

After the switch system is restarted successfully and the VRP platform software has been updated, it is necessary to carefully and carefully maintain the updated software, next, let's give some comments and opinions on the switch system. As a core network terminal in a LAN, maintaining the switch system becomes very important. In order to make the LAN work more s

Tab tab switch effect JavaScript Summary It is very common to switch tabs on current web pages.

Cocos2d-x trip _ 39] simulate a switch in LUA This is actually not difficult, but a friend told me that he encountered the question "Please use lua to simulate Switch" during the interview ...... I think of sharing my previous articles ...... The code is simple: _ G. switch = _ G. switch or {} _ G.

Slow network speed is a common type of switch failure. We need to carefully analyze the error records of the faulty switch so that we can fundamentally solve the problem and avoid repeated errors later. When the network scale is relatively large, the "load" of switches that shoulder network data forwarding, content filtering, and management control tasks will be very heavy. In addition, like a person's heal

As a network operations engineer, if the management of the routing, switching equipment more, then you will also encounter the same problem with me: The device configuration is often adjusted, especially the access layer switch, in case you forget to save the configuration, and the next day a switch power-down restart, you have forgotten the previous configuration, Causes the network restore configuration t

In recent years, with the rapid development of internet/intranet and the wide application of B/S computing mode, the business of cross region and network has been growing rapidly, and the industry and users have deeply felt the bottleneck effect of traditional routers in the network. The three-layer switch can operate on the third layer of the network protocol, play the role of routing decision, and have the speed of the second layer exchange, and the

the setting method of Tplink router switching working mode TP Mini Routers offer a variety of operating modes: Router (Router), AP (wireless access point), Repeater (relay), client (clients), Bridge (bridging), suitable for use in different network environments. Note: If it is a 3G mini router, there is also 3G mode. Used in different network environments, mini routers may need to switch to different working modes, such as using router mode at home
